简介：

Overview

This novel protocol entails the quantification of cardiovascular calcification from serial micro positron emission tomography (PET)/micro computed tomography (CT) images in small research animals. These imaging modalities are particularly advantageous for tracking vascular calcification in longitudinal studies.
